To all whom it may concern:

Be it known that we, WILLIAM HENRY More GAN and CLARENCE LANDFEAR TAYLOR, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Ingot-Extracting Apparatus; and we do hereby declare thelfollowing to be a full, clear, and exact description of the invention, such as will enable others skilled IO in the art to which it appertains to make and use the same.

Our invention relates to an improvement in in got-extracting apparatus; and it consists in the parts and combinations of parts, as will be more fully described,and pointed out in the claims. I r

In the accompanying drawings, Figure 1 is aviewin olevation,partlyin section,of our improved apparatus, showing simply thebridge,

2o trolley,rack-bar,and mechanism for actuating the mold-graspin g levers,the motors and gearing being omitted: Fig. 2 is a view of the lower end of the extractor, showing the grapplinglevers in a position to' enga ge the ingot-mold.

z 5 Fig. 3 is aiplan #view of the trolley, showing the motors and the square shaft and rack,

and Fig. 4 is a view showing the gearingcom; necting the square shaft and rack-bar.

A represents an overhead travelingbridge mounted at its endson rails 13 and carrying the traveling trolley O, the latter having flanged wheels which. travel on rails secured to the upper faces of the bridge-girders. This trolley C is propelled by the motor 0 3 5 and suitable'gearin g connecting the armatureshaft of the motor and two of the flanged track-Wheels. The bridge travels lengthwise the shaft and thetrolley lengthwise the bridge, so that rack-bar D, carried by the trolley, practically takes in the entire floorspace of the mill in which the bridge islocated. The rack-bar D is carried by the trolley and is actuated vertically by the pin-' ion 1 on shaft 2. This shaft is mounted in suitable bearings on the trolley G and carries at its outer end the gear 3, meshing with the smaller pinion 1 on-shaft 5. This shaft 5 carries a gear meshing with a smaller pinion on the armature-shaft 6 of the motor E, the

pinion 10 on the screw-shaft 11.

against rotary movement therein. construction it will be seen that as thepinion pinion on the armature-shaft and the pinion meshing therewith being inclosed by the gear-case 7. This motor E and the gearing above referred to operate to move the rackbar vertically, the bar being guided and sup: ported against the presence of the pinion 1 by the roller L. (Shown in Fig. 3.) The rackbar is, as shown in Fig. 3, in the form of the segment of a circle and is hollow, while the upper end thereof, which is cylindrical, is provided with male threads 8 for the attachment of the casing 8. This casing is hollow throughout its length and is provided near its lower end with a cylindrical enlargement 9, forminga casing for the pinion 10, mounted 011 the right and left hand screw-shaft 11, the

casing being open at one side for the engagement of the pinion 12 (shown in Fig. 4) with Secured to and within the upper open end of bar D is the bushing or bearing 13, which latter is screw-threaded internally to receive the lower screw 1 1 of the double screw 11, and as this bushing or bearing 13 is keyed to rack-barD it will be seen that as the screw is turned it ,rises or falls in bearing 13,the direction of movement being dependent on the direction of rotation of pinion 10.

Mounted in'the upper open end of the easing 8 is the hollow nut or sleeve 15. This sleeve is keyed to casing 8, so as to prevent its rotation therein, and carries at its lower end the femalethreaded bushing 16, thelatter being keyed to sleeve 15, so as to be held With this 10 isrotated it turns screw-shaft 11, and as thelatter is coupled up to the pinion by a spline and groove the screw is, elevated, thus lifting sleeve 15. The screw, however, is

turned in the screw threaded bushing 16, and 'as the latter is keyed to the sleeve 15 it foldirection.

Secured to the upper end of sleeve or nut 15 is the cross-head 17. This cross-head projects from opposite sides of the nut or sleeve 15 and carries and supports the rods 18, which latter support the movable cross-head 19. Cross-head 19 is provided centrally with a hub which embraces the ingot-holding plunger 20 and carries the bell-crank mold-stripping levers 21, each of which is provided with a looped lower end adapted to receive the ears 22 on the ingot-mold 23. The plunger 20 is secured to the lower end of rack-bar D and is designed to enter the smaller end of the mold and bear against the ingot and. hold the latter against movement while the mold 23 is being stripped therefrom by the upward movement of the bell crank levers. The bell-crank levers are owing to their construction adapted to normally swing or rest, so that their looped ends are in contact with the sides of the mold in position to engage the ears 22 when the rack-bar is lifted and are disengaged by the rods 24:, the lower headed ends of which pass through openings in the outer ends of the horizontal members of the bell-crank levers, while their upper ends pass through openings in the ends of bracket 25 and are supported on springs 26, carried by said bracket. The bracket is secured to the rack-bar D, while the cross-head is loose on the plunger. Hence it will be seen that if the cross-head 19 be moved toward the bracket 25, as shown in Fig. 2, the rods 24 release the bell-cranks, thus permitting the looped ends of the levers to swing into contact with the sides of the mold in position to engage the ears 22 when the rack-bar is lifted.

The pinion 10 on screw 14 is engaged by pinion 12 on square shaft 27. Pinion 12 rests on bracket 28, carried by the rack-bar D, and square shaft 27 passes through an openingin the bracket and through an angular opening in pinion 12 and transmits motion to the latter, and as the pinion is free to slide on the rack-bar it will be seen that the pinion 12 fol-- lows the rack-bar in its vertical movements and may be rotated while at any point of its movement by the square shaft 27. This square shaft is mounted in bearings on the trolley and carries at its lower end a bevelpinion 28, which is engaged by bevel-pinion 29 on shaft 30. This shaft carries the large toothed wheel 31, which meshes with a smaller pinion 32 on the armature-shaft of the motor 33. This bracket 28 when in its lowest position engages the seat or rest 29, carried by the trolley. From this construction it will be seen that by rotating the square shaft 27 pinion 10 on screw 11 will be rotated, and as the screw is, as before explained, connected to the pinion 10 by a spline and groove the screw is caused to move longitudinally in its bearing 13 and the nut or sleeve 15 caused to move on the screw. Hence if the screw be turned in a direction to elevate the nut or sleeve 15 it will be seen that the rods 18 pull up the cross-heads 19 toward bracket 25, thus releasing the levers 21 from the rods 24.

Assuming now that the mold 23 (shown in Fig. 1) contains an ingot. To strip the mold from the ingot, the stripper, with the parts in the position shown in Fig. 1, would be brought to a position over the ingot, after which the rack-bar would be lowered, so as to bring the plungerinto contact with theingot,after which motion would be imparted to pinion 10 by the square shaft and mechanism before explained in a direction to elevate the nut or sleeve 15. This upward movement of the nut or sleeve 15 and rods 18, carried thereby, operate to first release the levers 22, so that the latter may engage the ears 22 of the mold, while the .continued upward movement of the sleeve 15 operates to strip the mold from the ingot, the latter being solidly held against movement by the plunger 20, which during the movements last described remains stationary. The stripping power imparted by the screw is necessarily slow but powerful. Hence just as soon as the mold separates from the ingot motor E is thrown into circuit and the rack-bar lifted, thus elevating the mold above the ingot. The bridge and trolley are thus operated to carry the mold to its proper place, after which the stripper returns to the next mold to be stripped.

In order to take the weight of the rack-bar off the motor E, we have provided a tower F for carryinga counterweight G. This counterweight is made with an open center, as shown in Fig. 1, so as to permit of the free vertical movement of the rack-bar through the same, and is connected to the latter by chains H, passing over sheaves I at the top of the tower.

While the empty mold is being removed, the direction of rotation of the screw 11 may be reversed, thus lowering the cross-head 19 to its lowest position. This of course would lower the stripping-levers onto the heads of the releasing-rods 21; but as the weight of the mold is greater than the tension of the springs 26 the latter will be simply compressed until the mold has been deposited on a car or floor. As soon as the weight is removed from the levers 21 the springs 26 cause the levers to fly open to the position shown in Fig. 1.

It is evident that many slight changes might be resorted to in the relative arrangement of parts herein shown and described without departing from the spirit and scope of our invention. Hence we would have it understood that we do not wish to restrict ourselves to the exact construction herein shown and described; but,
